FT index on AS400

After upgrading a Domino server from 7.0.2 to 8.0.1 on AS400 V6R1 I’ve problem with FT index.

Scenario:

A database contains cca 20 documents. A typical document has usually 3-5 attachments. Average size of a document is 2-3 MB.

  1. When I search without FT index I don’t have any problem.

  2. When I search with FT index I’ve problem with opening documents. LN client become deadly slow when opening an document from the results of the find documents.

  3. When I clear FT index, search is OK again

searching was all right before upgrade…

Does anyone have any experience with this?
